About Us

30 Million Glasses of Wine Purified… and Counting

At Üllo, we believe wine is best enjoyed in its purest form—the way the winemaker intended. Free from the artificial sulphite preservatives added during production and with lower histamines, wine in its natural state delivers the true taste, aroma, and experience that wine lovers deserve.

Since our founding in 2015, Üllo has been on a mission to transform how the world enjoys wine. With over 30 million glasses purified and counting, we’re proud to serve hundreds of thousands of customers worldwide who are discovering the joy of pure, sulphite-free wine.

The Story Behind Üllo

Üllo was founded by James Kornacki, Ph.D., an American chemist and inventor passionate about enhancing the wine experience. Driven by a desire to create a solution for sulphite-sensitive wine lovers, James invented Selective Sulphite™ technology, a groundbreaking method to remove sulphites from wine without affecting its natural flavours and aromas.

"My aunt is sulphite sensitive and couldn’t enjoy wine at our family gatherings. When I read that others had similar reactions, I felt the need to create a solution. With my background in chemistry, I had the knowledge to make it happen."


— James Kornacki, Ph.D., Founder & CEO

With a doctorate in chemistry from Northwestern University, James brought his vision to life by launching the Üllo Wine Purifier, the first product of its kind.

What Does "Üllo" Mean?

The "Ü" in Üllo is inspired by the alchemy symbol for purification, reflecting our mission to deliver wine in its purest form. Pronounced “oo-low,” Üllo is dedicated to helping wine lovers everywhere savour wine the way it was meant to be—simple, pure, and natural.

The Heart of Üllo

At Üllo, we believe wine is at its best when it’s free from artificial sulphites and with lower histamines. These unnecessary preservatives, while useful for winemaking and storage, can often interfere with wine’s true flavour.

That’s why we designed our products to remove sulphites while preserving the natural integrity of wine, so every sip is as close to the vineyard as possible.

A Community That Believed in Us

Üllo’s journey wouldn’t have been possible without a passionate community of supporters. Through a crowdfunding campaign, over 2,000 backers pledged more than $250,000, helping turn Üllo from an idea into a reality.

Today, we remain inspired by that incredible support and are committed to continuing innovation for wine lovers worldwide.
